The typhoon-stricken Philippines is bracing for the post-disaster impacts. Aid has been slow to trickle in and many in the country who are displaced and hungry have turned to looting. (Published Wednesday, Nov. 13, 2013)

Typhoon Haiyan, which struck six central Philippine islands this month, was the strongest typhoon of the year and one of the strongest storms on record.

Estimates of the number of people it has killed vary, but the Phillipines government put the death toll Saturday at 3,637 deaths.

Millions of residents are in desperate need of drinking water and food. Several organizations are deploying urgent relief efforts on the islands, according to a list compiled by NBC News. Most organizations are asking for monetary donations, so they can help provide relief. Find out how to help:
